, Business , Sources of Revenues, for a table identifying the sources and relative payor mix of our revenues. In addition to many ordinary course reimbursement rate changes that The Centers for Medicare & Medicaid Services ( CMS ) of the U.S. Department of Health and Human Services ( HHS ) adopts each year as part of its annual rulemaking process for various healthcare provider categories, Congress and some state legislatures have periodically proposed significant changes in laws and regulations governing the healthcare system. Many of these changes have resulted in limitations on the increases in and, in some cases, significant roll-backs or reductions in the levels of payments to healthcare providers for services under many government reimbursement programs. There can be no assurance that future governmental initiatives will not result in reimbursement freezes and reductions, or reimbursement increases that are less than the increases we experience in our costs of operation. In March 2010, President Obama signed into law the Patient Protection and Affordable Care Act of 2010 (the ACA ) as a significant healthcare reform. Many provisions within the ACA have impacted or could in the future impact our business, including Medicare reimbursement reductions and promotion of alternative payment models, such as accountable care organizations ( ACOs ) and bundled payment initiatives.
